Eber (עֵבֶר, Standard Hebrew ʿÉver, Tiberian Hebrew ʿĒḇer, Arabic: ھود) or Heber, is a person from the Hebrew Bible and Muslim Qur'an. He was a great-grandson of Noah's son Shem and the father of Peleg and Joktan. He was the son of Salah and an ancestor of Abraham.

In Jewish tradition, Eber, the great-grandson of Shem, refused to help with the building of the Tower of Babel, so his language was not confused when it was abandoned. He and his family alone retained the original human language, Hebrew, a language named after Eber (Heber), also called lingua humana in Latin. (There are different religious positions on this issue; see also Adamic language.)
